Remedial sealant across Merston and nearby, with old sealant always removed completely.

- Gaps opening along the back of the worktop
- Mould trapped under a layer of silicone
How we handle remedial sealant in Merston
If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. Typical jobs include decorators’ caulk around a bath or shower and black mould underneath the bead, across expansion joints, failed movement joints and botched or over-sealed joints.
For a small place like Merston, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Merston needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Mention any parking rules near the property
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. It needs fixing down first, which we’ll point out.
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
What affects the quote in Merston
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.
What we need to know
When you contact us, it’s useful to know:
- If it’s domestic, commercial or a hotel
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- The address or postcode of the job
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or email us.
Bathrooms and kitchens in Merston
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Chichester station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like North Mundham Primary School? Then washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Homes close to Church of St Giles include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep bleach and abrasives off the bead
- Have loose fittings fixed before resealing
- Never fill a movement joint with mortar or grout
- Always have old sealant cut out, not covered
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Common questions in Merston
Do you cover smaller places like Merston?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Chichester station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
What do you need from me for a quote?
Tell us what needs doing and where, with photos by email if possible. If we need more, we will ask.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What if the leak isn’t the sealant?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, and we won’t reseal for the sake of it.
Why act early in Merston
Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Merston, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
